THOMAS GRAHAWI HAMILTON, OF GABY, INDIANA.

RAILWAY TIE.

Application filed July 29,

To all whom it may concern.'

Be it known that I, THOMAS Gr. HAMIL- Ton, a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented certain new and Auseful Improvements in Railway Ties. of which the following is a specification.

My present invention relates to improvements in metallic railway ties and it has special reference to that type of railway tie disclosed in my patent dated August 20, 1907, No. 863,987. i

The tie disclosed in my patent aforesaid consists of single piece of'plate metal bent or otherwise shaped into the finished tie without any connecting or supplementing holding elements except devices for holding the rails thereon.

My present invention has for its purpose to provide a tie of substantially the same shape as that of my patented tie except that the tie body is formed vof two like opposing longitudinal half sections having engaging flat ends adapted for overlapping in such manner that they may be readily secured by riveting, and when secured extend along the length of the tie suiciently to provide under bearing or base portions for the rail supporting lends of the tie only, whereby to provide a tie whose top is open the full length thereof and whose bottom is likewise open along the length of the tie between the opposite closed bottom or base portions to thereby materially cheapen the cost of mant' ufacture of the type of tie shown in my patent aforesaid and make it possible' to produce the tie by either rolling or pressing the two half sections into the desired form.

Another object of my present invention is to provide an improved construction of tie embodying the same general characteristics present in my patented tie mentioned, composed of two like opposing longitudinal sections designed to provide increased facilities for tamping the tie base along the rail bearing ends thereof and for obtaining a greater ballasting effect along the full length of the tie than is possible to obtain when the base of the tie is in the nature of a continuous solid bottom trough, as in my patented tie, before mentioned.

With the above general objects in view my present invention is an all metal railway tie which embodies the peculiar features of construction and novel arrangement of 1922. Serial N0. 578,418.

parts, all of which will be hereinafter fully explained, specifically pointed 'out in the ap-` pended claims and illustrated in the accom-v panying drawing, in which:

Figure l is a side elevation of one end of my improved railway tie with the rail secured thereon.

Figure 2 is a plan view `of the tie portion shown in Figure l.

Figure 3 is an end elevation of the tie with the rail thereon and looking in the din rection of the arrow on Figure l.

Figure et is a perspective view of the two half sections of the tie separated. i

Figure 5 is a cross sectionof my improved tie taken on the line 5-5 of Figure l.

In my present construction of metal railway tie, the body portion of the tie is composed of two longitudinally opposing like shaped half sections, the peculiar shape of which, after the said sections are bent to shape, is best shown in Figure s, which shows that each section is a Asheet metal blank bent upwardly and inwardly, as indicated by 3, and then outwardly. the full length thereof as at 4l, it being understood from the drawing, the flangesA--liY of the opposing half sections project in opposite direction in planes parallel with the inwardly bent base portions 2 which7 in my present construction, extend along each end only sufficient to provide base portions (in practice, extending from each end) from the rail bearing ends of the tie.

In myy present form of tie, the side portions of each section do not extend the full height of the tie, the same being cut out the full length thereof between the rail bearing ends. at which points the sides 3 extend down the full height of the tie and merge with the inturned dat base portions 2, the portions of the sides 3 between the rail bearingn ends in my present tie structure form, as it were, shallow webs that connect and constitute the stifteners for the opposite ends or bearing portions if each tie section.

By reason of forming the tie body of two half sections as shown and described. the said half sections can be made by rolling, or pressed into the form shown, and by cutting out the base or trough portions, present in my patented tie mentioned, and also the greater portion of the sides 3 between tbe aforesaid rail bearing ends of llO the tie, the Weight of the material of which the tie is formed and the cost of making the tie isgreatly reduced. y

A further advantageous feature of' my construction of tie, as shown and described isA that by making the base portions 2 Sulliciently wide to overlap, as shown in Figure 3, the said portions can be readily secured as solid base ends by riveting them together as shown at 20-20. f

lVhen assembling the two opposing half sections of the tie the upper ends of' the side portions 4 are sufliciently separated to provide ample space 5 for receiving the ballast which, in my present construction, fills through the open sides of the tie and also through the open bottom ofthe tiev body, asv is clearly shown in Figure 5.

To further provide for effectively ballast ing the tie body, the base portions 2, at the rail bearing ends, are cut out t0 provide tamping openings 21, the said openings 21 being of sullicient length that their ends 21a are exposed at each side of the rail to facilitate tamping when the rails are applied.

In my present construction of tie, the rail bearing ends thereof are inwardly pressed, as indicated at 11, to provide inwardly extending stiffening braces of upwardly tapering form,` and similar elements 12 are provided by pressing the merging portions of the upper ends of the sides 3 and the lateral flanges the same as in my patented tie before referred to.

From the foregoing description, taken in connection with the drawing, the complete construction of my present railway tie and its advantages will be apparent to those familiar with the use and the manufacture of metallic railway ties of the general character described and shown.

What I claim is:

1. A metallic railway tie formed of two' of and merges at the ends with the side portions at the opposite ends, the top edge of each section terminating in outwardly extending flanges that constitute the rests for the rails, the base portions of the two opposing' sections being adapted for overlapping, and means for rigidly connecting the p said lapped base portions.

2. A metallic railway tie formed of two like opposing halfl sections each bent at the opposite ends Athereof to provide flat base portions and sloping side portions, and

with a web portion that extends lengthwise f tached base portions each having a slot-` way that extends lengthwise thereof and whose ends project beyond the transverse confines `of' the rail bases that seat 'across the top flanges of the said opposing sec-l tions.

3. A metallic railway tie formed oftwov longitudinal half sections bent along their opposite ends to form. wide base portions and inwardly and upwardly sloping sides terminating at the upper end in outwardly extendingweb flanges, the said base portions of the two sections being adapted for overlapping, means for securing the overlapping base portions to space the two sections apart to provide` an intervening longitudinal space along the top face ofl the tie, each of the opposing sections including a longitudinal side web along the upper edge that merges with the vtop flanges and with thek sloping side portions at the opposite ends whereby to provide for the reception of ballast around the said webs and between the opposing sides at the opposite ends of the body.
